LAGO RUNNER: Thanks for your feedback! I have friends who are Motor Patrol Officers here in Arizona: DPS, Scottsdale, Gilbert, Chandler, Phoenix and the other municipalities that utilize the R1150RTP Authority bikes; some are members of AZ Beemers. They put on approximately 200 miles a day, working out to 1K miles a week on their police bikes. They relate to me that they top off with about a third of a quart of oil a week. However, all these machines have less than 50,000 miles.
I follow the same guidelines as wel1123 does and change the oil on my two BMW's, FJR, H-D FXD every 3,000 miles. My Kawasaki KLR 650 gets its oil changed every 1.5K miles because it is constantly run off road under really grimy conditions.
The oil usage on these Arizona R1150RTP's is close to the same as my civilian R1150RT; I will be at least a half quart low at oil change time. Ironically, my 1996 R1100GS doesn't use a drop of oil between changes. But this is now at 110,000 miles.
What is the mileage on your Authority R1150RTP? Could it be that the rings have still not seated on the NIKASIL cylinder liners? Up until 50,000 miles the R1100GS was also using a third of a quart every 1K miles. Rings were still not fully seated!
fjrb0: Glad you enjoyed the Devil's Highway. They're forecasting possible snow and hail this Sunday. Wacky AZ Weather!
